[0023] Combination Figures 1-4 A biomedical culture dish includes a dish body 1, four partitions 2 fixedly installed inside the dish body 1, an opening and closing component 3 installed on the top of the dish body 1, and a sealing component 4 installed on the outside of the dish body 1.

[0024] See Figure 2 Furthermore, the opening and closing assembly 3 includes a sealing sleeve 5 and a positioning plate 6. The sealing sleeve 5 is installed on the outside of the vessel body 1 near the top. The positioning plate 6 is fixedly installed on the inner ring of the sealing sleeve 5. A positioning groove 7 is provided at the bottom of the positioning plate 6. Cover plates 8 are movably installed on both sides of the positioning plate 6. A hinge pin 9 is installed between the cover plate 8 and the positioning plate 6. A slot 10 is provided at the bottom of the cover plate 8. A positioning frame 11 is fixedly installed on the top of the cover plate 8 near the outer side. A positioning bolt 12 is movably installed through the top of the positioning frame 11. Two positioning holes 13 are provided at the top of the sealing sleeve 5.

[0025] The top view of the four partitions 2 is arranged in a cross shape. The longitudinal partitions 2 are interlocked with the positioning grooves 7, and the transverse partitions 2 are interlocked with the slots 10. The four partitions 2 are used to divide the internal space of the dish 1 to facilitate the cultivation of various organisms.

[0026] The cover plate 8 and the positioning plate 6 are movably connected by a hinge shaft 9. The two cover plates 8 are symmetrical to each other. When the two cover plates 8 are closed, they are used to open and close the two culture spaces separately.

The retaining ring 15 and the sealing sleeve 5 are fixed to each other. The retaining ring 15 is located inside the connecting sleeve 14 and is rotatably arranged. The connecting sleeve 14 is connected to the sealing sleeve 5 through the retaining ring 15 to avoid cross-infection in each culture space caused by the rotation of the sealing sleeve 5.

[0032] The inner wall of the inner ring of the connecting sleeve 14 is provided with threads, and the connecting sleeve 14 and the threaded groove 16 are connected by threads. By rotating the connecting sleeve 14 and the threaded groove 16, the sealing sleeve 5 can be disassembled for overall cleaning.

[0033] Specifically, the connecting sleeve 14 is located outside the dish body 1 and connected to the threaded groove 16, so that the sealing sleeve 5 is fixed outside the dish body 1. Through the connection of the retaining ring 15, the partition 2 is engaged with the positioning groove 7 to prevent the sealing sleeve 5 and the cover plate 8 from rotating, thereby reducing cross-contamination of the culture space.

[0034] In actual operation, various biological materials are added into the dish 1 respectively, and the biological materials in the dish 1 are cultured separately by four partitions 2. The inside is sealed by the sealing sleeve 5 and the cover plate 8.

[0035] When opening and closing, the sealing sleeve 5 is fixed to the outside of the dish body 1, the longitudinal partition 2 is inserted into the positioning groove 7, the transverse partition 2 is inserted into the slot 10, and the positioning bolt 12 is connected or disconnected from the positioning hole 13. The cover plate 8 is connected to the positioning plate 6 through the hinge shaft 9, so that the corresponding two culture spaces can be opened or closed for observation and operation.

[0036] When sealing and fixing, the connecting sleeve 14 and the sealing sleeve 5 are located outside the dish body 1. By rotating the connecting sleeve 14, the connecting sleeve 14 is connected to the threaded groove 16 to fix the sealing sleeve 5. Through the connection of the connecting sleeve 14 and the retaining ring 15, the partition 2 is engaged with the positioning groove 7 to prevent the sealing sleeve 5 and the cover plate 8 from rotating, thereby reducing cross-contamination of the culture space.
